The Environmental Protection Agency (EPA) released the draft National Pollutant Discharge Elimination System (NPDES) permit for point source discharges from the application of pesticides to waters of the United States.
EPA developed the general permit in response to a decision by the Sixth Circuit Court of Appeals (National Cotton Council, et al. v. EPA). The court vacated EPA's 2006 rule that exempted FIFRA-compliant aquatic pesticide applications from the Clean Water Act requirements. Due to the Sixth Circuit's decision, by April 9, 2011, aquatic pesticide applications will require NPDES permits.
EPA's draft permit regulates four pesticide use patterns: (1) mosquito and other flying insect pest control, (2) aquatic weed and algae control, (3) aquatic nuisance animal control, and (4) forest canopy pest control.
